QUESTION NO: 1
You administer a Microsoft SQL Server 2016 database named Orders.
Users report that during peak usage periods, certain operations are taking more time than expected.
Your initial analysis suggests that blocking is the cause.
You need to gather more data to be able to determine which processes are being blocked and to identify the root cause.
What should you do?
A. Use System Monitor to catch the Lock Waits/sec event.
B. Start a trace using SQL Server Profiler to catch the Lock: Deadlock event.
C. Schedule a SQL Agent job to run every 60 seconds and insert the results of executing the sys.dm_os_wait_stats DMV into a table.
D. Use sp_configure to set the blocked process threshold. Start a trace using SQL Server Profiler to catch the Blocked Process Report event.
Answer: D

QUESTION NO: 2
You are designing a Windows Azure SQL Database for an order fulfillment system.
You create a table named Sales.Orders with the following script.
Each order is tracked by using one of the following statuses:
* Fulfilled
* Shipped
* Ordered
* Received
You need to design the database to ensure that that you can retrieve the following information:
* The current status of an order
* The previous status of an order.
* The date when the status changed.
* The solution must minimize storage.
More than one answer choice may achieve the goal. Select the BEST answer.
A. To the Sales.Orders table, add three columns named Status, PreviousStatus and ChangeDate.
Update rows as the order status changes.
B. To the Sales.Orders table, add three columns named FulfilledDate, ShippedDate, and
ReceivedDate. Update the value of each column from null to the appropriate date as the order status changes.
C. Implement change data capture on the Sales.Orders table.
D. Create a new table named Sales.OrderStatus that contains three columns named OrderID,
StatusDate, and Status. Insert new rows into the table as the order status changes.
Answer: D

QUESTION NO: 3
DRAG DROP
You plan to install two SQL Server 2014 environments named Environment1 and Environment2. Your company identifies the following availability requirements for each environment:
* Environment1 must have mirroring with automatic failover implemented.
* Environment2 must have Always On with automatic failover implemented.
You need to identify the minimum number of SQL Server 2014 servers that must be deployed to each environment to ensure that all data remains available if a physical server fails.
How many servers should you identify? To answer, drag the appropriate number to the correct environment in the answer area.
Answer:
Explanation:
Environment1 - 3; Environment2 - 2

QUESTION NO: 4
DRAG DROP
You administer a SQL Server instance. A database named DB1 is corrupted.
Backups of DB1 are available on a disk backup device located at Z:\Backups\Backup.bak.
The backup device has the following backups sets:
* a full database backup that is the first backup set on the device (FILE = 1)
* a differential database backup that is the second backup set on the device (FILE = 2)
* a transaction log backup that is the third backup set on the device (FILE = 3) You restore the full database backup and the differential database backup without rolling back the uncommitted transactions.
You need to restore the transaction log backup and ensure the database is ready for use after restoring the transaction log.
How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-
SQL segments to the correct locations. Each Transact-SQL segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
Answer:
Explanation:
The RESTORE restores backups taken using the BACKUP command. You can do restore a transaction log onto a database (a transaction log restore).
NORECOVERY specifies that roll back not occur. This allows roll forward to continue with the next statement in the sequence. In this case, the restore sequence can restore other backups and roll them forward.
RECOVERY (the default) indicates that roll back should be performed after roll forward is completed for the current backup.
Recovering the database requires that the entire set of data being restored (the roll forward set) is consistent with the database. If the roll forward set has not been rolled forward far enough to be consistent with the database and RECOVERY is specified, the Database Engine issues an error.

QUESTION NO: 5
You administer a Microsoft SQL Server 2016 instance.
You discover that the SQL Agent Error Log file is rapidly growing in size.
You need to ensure that the SQL Agent Error Log file does not grow rapidly when SQL Server agent jobs execute.
What should you do?
A. Disable the Include execution trace messages feature.
B. Configure event forwarding.
C. Enable the Auto Shrink option on the msdb database.
D. Enable the Auto Shrink option on the master database.
E. Execute the sp_cycle_agent_errorlog stored procedure.
Answer: A
Explanation:
Because the Include execution trace messages option can cause the error log to become large, only include execution trace messages in SQL Server Agent error logs when investigating a specific SQL
Server Agent problem.
